Barriers and facilitating factors in the prevention of diabetes type II and gestational diabetes in vulnerable groups: protocol for a scoping review.

BACKGROUND: There is a significant worldwide increase in type 2 diabetes mellitus and gestational diabetes (T2DM/GDM) linked to a range of associated comorbidities and rising healthcare costs. It has been shown that an increase in physical activity, healthy nutrition, and weight loss may prevent or delay T2DM/GDM manifestation. Despite this, it remains a key challenge to reach various populations, in particular so-called vulnerable groups, mostly with a migration background and/or low socio-economic status.

METHODS/DESIGN: We will conduct a scoping review to identify barriers and facilitating factors in the prevention of T2DM/GDM in vulnerable groups. An electronic literature search will be performed in MEDLINE, EMBASE, PsycINFO, PSYNDEX, Social Science Citation Index, and CINAHL. Two reviewers will independently select studies for inclusion. Extracted data will be charted, categorized, and summarized.

DISCUSSION: The results will be used to inform the National education and communication strategy on diabetes mellitus in Germany. In particular, the results will be discussed in focus groups of experts to develop recommendations for developing preventive measures targeting vulnerable groups.

SYSTEMATIC REVIEW REGISTRATION: PROSPERO does not register scoping reviews.
